Enterprises Urged to Adopt a More Strategic Approach to Application Delivery, Now

Today, IT departments employ a variety of point solutions and technologies in order to accommodate flexible working practices. With the trend for mobility showing no sign of abating, now is the time for IT departments to adopt a holistic approach to application delivery and IT infrastructure access.

Europe’s IT research and advisory organization Butler Group believes that the importance of providing key applications to remote workers and of extending business processes to distributed locations either through fixed or wireless communication technologies cannot be overstated. The report “Application Delivery – Creating a Flexible, Service-centric Network Architecture” identifies that application delivery to the extended enterprise allows organizations to improve processes and presents an opportunity for innovation within organizations, offering new freedoms that will eventually change the way companies interact with customers, partners, and employees.

“The effect of changing social patterns on business models cannot be ignored, with more and more of the workforce now based away from head office,” says Mark Blowers, senior research analyst and co-author of the study. “A growing proportion of the workforce is also becoming more mobile, meaning that organizations must cater for them in corporate and IT strategies. The expectation is that it will be possible to work remotely, roam freely, and be able to use any type of device.” “However, there is an increased business risk to this freedom, with the main issues being the security of information outside the confines of the office and the ability to effectively manage the wider environment.”

The performance of remote services and optimization of application delivery are key issues for IT managers.
Managing connections for the entire workforce, especially mobile workers in the field, can prove to be a complex task. With users connecting via a wide range of fixed and wireless networks, ensuring seamless connectivity while also controlling costs can be a headache. Session persistence, airtime management, and roaming between wireless networks are also a part of this responsibility. In addition, both fixed and wireless networks need to be administered as a single entity.

Many remotely accessed applications are mission-critical but face issues with centralization, poor performance, reliability, and security. The IT department first must deploy the means to measure, and second, implement tactical and strategic mechanisms to improve the performance for remote users. With the WAN optimization solutions available today, a major barrier to consolidation is removed through the significant improvement in application performance at remote locations. It is recommended that organizations with branch offices must look at trialing a WAN optimization solution.

“Management is a key component in an application delivery architecture where policies drive availability, and visibility moves from individual point solutions to being system-wide, along with the shift from fixed-asset administration to dynamic asset utilization,” continues Blowers. “A cornerstone for the provision of multi-modal channels is the ability to deliver intelligent central management, enabling efficient use of the available resources. The accessibility of end-to-end QoS supporting data, voice, and multimedia is an important first step in the evolution to an automated solution.”

Security is a key concern, although it should not be a barrier to the adoption of more flexible working practices.
A May 2007 Datamonitor survey of 500 IT decision makers identified a number of factors as the primary inhibitors to investment in mobile technologies. Security is still perceived to be an issue—enterprises list security concerns as the top inhibitor, with the scares of Internet breaches and data leakage causing enterprises to be cautious when considering or deploying mobility solutions. This also may be due to a lack of understanding of security technologies.

With more organizations choosing to incorporate flexible user access facilities, including the use of local and remote wireless network approaches, there is a need to understand the associated risks as well as the benefits that should be taken into account when considering such a strategy. The risks include data loss and data leakage, eavesdropping on transmissions, the ability of third parties to intercept wireless communications, the lack of central control, and reduced connection controls.

Blowers concludes: “Customers, employees, business partners, suppliers, and contractors need to be properly and adequately protected each time they access applications. Within this context, there is a requirement for operational security solutions that have the scalability to deal with high-volume access requests, are comprehensive enough to handle all different levels of user and systems protection demands, and still retain the functional granularity that is needed to deal with each user as an individual when assessing their security status.”
